Despite ignoring Brokeback entirely, the SAG awards resembled the Golden Globes in other ways, namely in their choices for best actor (Philip Seymour Hoffman), actress (Reese Witherspoon), and supporting actress (Rachel Weisz) - and they also honored Sandra Oh for her work on Grey's Anatomy, as the Hollywood Foreign Press did. The other movie awards went to Oh's Sideways costar Paul Giamatti (best supporting actor for Cinderella Man) and the cast of Crash, which was voted best ensemble.
Though the absence of Brokeback is initially shocking, the film hasn't exactly been piling up acting awards - it's been Lee and the movie in general that win. So, in that way, SAG actually followed the script more closely than it would initially appear. While Heath Ledger has showed up on all the of lists of best actor nominees, he's only been the winner of a few regional (New York, San Francisco) critics' awards. If the Academy follows this trend, while we can be pretty sure his name will be included tomorrow morning when the nominees are revealed, a win seems increasingly unlikely.
